A6.3 - Sound Velocity Profiles in Fluids for Process Monitoring

M. Lenz & E. Kühnicke
In conventional methods the sound velocity is determined by means of the back wall echo or a reflector at a known position. This paper presents a novel approach for combined measurement of sound velocities and distances in fluids with scattering particles. In contrast to conventional methods, the knowledge about the sound field is exploited to characterise the fluid, and solely the echoes from the scattering particles are used to determine sound velocity. The basic idea...
